The dilute A₄ model, the E₇ mass spectrum and the tricritical Ising model
The exact perturbation approach is used to derive the (seven) elementary correlation lengths and related mass gaps of the two-dimensional dilute A₄ lattice model in regime 2⁻ from the Bethe ansatz solution. This model provides a realisation of the integrable ϕ(1,2) perturbation of the c=7/10 conformal field theory, which is known to describe the off-critical thermal behaviour of the tricritical Ising model. The E₇masses predicted from purely elastic scattering theory follow in the...[Show more]
